Genes affected
BAZ2B (HGNC:963): (bromodomain adjacent to zinc finger domain 2B) This gene belongs to the bromodomain gene family. Members of this gene family encode proteins that are integral components of chromatin remodeling complexes. The encoded protein showed strong preference for the activating H3K14Ac mark in a histone peptide screen, suggesting a potential role in transcriptional activation. This gene may be associated with susceptibility to sudden cardiac death (SCD). [provided by RefSeq, Aug 2016]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.15243214).
BS1
Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00002 (28/1402752) while in subpopulation EAS AF = 0.000287 (10/34842). AF 95% confidence interval is 0.000155. There are 0 homozygotes in GnomAdExome4. There are 12 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 28 AD gene.
